The Explore Scientific 30mm 82° Series Waterproof Eyepiece is the perfect blend of immersive wide-field viewing and long-session comfort. With a sweeping 82° apparent field of view, this ultra-wide eyepiece draws you into the night sky—ideal for observing nebulae, globular clusters, comets, and more.
A generous 22mm eye relief allows for relaxed viewing, even while wearing glasses. Whether you’re observing for minutes or hours, this eyepiece delivers rich detail without visual fatigue. Pair it with an Explore Scientific Focal Extender to double or triple your magnification without sacrificing field of view or eye comfort.
Built with high-refractive index, low dispersion glass, fully EMD-coated optics, and edge-blackened lenses, this eyepiece ensures brilliant contrast, sharp resolution, and minimal internal reflections. The argon-purged, waterproof housing protects your optics from fogging, moisture, and dust—so you can focus on the cosmos, not the conditions.
